Obama might be the worst president in modern US history. I certainly would not use his actions to validate anything. It was wrong then and is wrong now. It has nothing to do with Obama, Trump. Or Democrat, Republican. Or Left, Right. The fact that a president can unilaterally bomb another sovereign nation and kill its citizens without Congress' (the people's) consent is heinously troublesome. I don't think US foreign policy is righteous. In fact on the contrary, probably for about the last 80 years US foreign policy has been overall terrible, and has not been in the best interest of the American citizen. I think there is ample evidence to support this. Murder hornets are more of a threat to US citizens than Iran is. But we just spent half a billion dollars leveling sections of their country for our safety. Anecdotally I fell less safe now than I did last Friday afternoon. Not by much but the feeling is there. I think the US meddling in Israel's matters is not in the US citizen's best interest.
It matters not but for the record it was more than 75 according to General Dan Caine, chairman of the Joint Chiefs of Staff. As I understand it the third site was leveled using dozens of cruise missiles launched from submarines due to it not being a fortified, underground site.
